Which of these is critical for ladder safety?

The critical aspect of ladder safety is the inspection and marking of the ladder before use. Ensuring that the ladder is free from defects and properly maintained is essential to prevent accidents and injuries. This involves checking for broken rungs, loose screws, wear and tear, and any other potential hazards that may compromise the ladder's structural integrity. Marking the ladder with information about its safety status can help users know whether it is safe to use or needs to be repaired or replaced.

Using a ladder with multiple employees at once can create an unstable environment and increase the risk of falls. Likewise, using a ladder regardless of its condition ignores potential risks that can lead to dangerous situations. Additionally, placing a ladder only on soft surfaces may not provide adequate stability; ladders should be on firm, level surfaces to ensure safety. Therefore, the inspection and appropriate marking of the ladder are paramount to ensure safe usage.
